Eventful fairy tale based on a popular book by Neil Gaiman about a star that falls to earth in human form (Claire Danes), and how she's pursued by a witch (Michelle Pfeiffer) who hopes to acquire eternal youth, a murderous prince (Mark Strong) trying to secure his late father's (Peter O'Toole) throne, and a young man (Charlie Cox) who promises the maiden (Sienna Miller) he loves that he'll bring her the star to prove his love. Matthew Vaughn directs the multistrand narrative with conviction, and there's a good deal of welcome humor and an interesting cast (also including Robert De Niro, Rupert Everett and Ricky Gervais) but some of the story elements veer more toward adults -- or older teens -- than the youngsters who might most enjoy this sort of yarn. Intense action violence, implied premarital sex, a flamboyantly gay character, another born out of wedlock, some innuendo and brief crass language. The USCCB Office for Film & Broadcasting classification is A-III -- adults. The Motion Picture Association of America rating is PG-13 -- parents strongly cautioned. Some material may be inappropriate for children under 13.
